I cannot really tell a big difference after one week. My skin is certainly starting to get really dry and flaky. I have been doing the steps morning and night. It takes a long time to do everything, but I guess you have to do what you have to do. Obagi has given people beautiful flawless results. As much as I would like to think that I was born with all my freckles, I know that is not true. Freckles are caused from sun damage and I have A LOT of them. I can't wait until week two!
